A reference guide for Mistral Vibe, the command-line coding agent running the session. It explains Vibe's setup, configuration, files, behavior, and troubleshooting.

Use it to inspect or change Vibe configuration, understand why it acted or did not act, and find guidance for using the Vibe CLI.

It gives the agent accurate context for answering questions about its own commands, settings, actions, and installation instead of guessing.

vibe — Skill for Claude Code by mistralai/mistral-vibe

About the project

Mistral Vibe is a command-line coding assistant that lets users converse with a codebase and use natural language to explore or change projects. Developers use it for file editing, code searching, version-control tasks, and shell commands through Mistral’s models. Its catalogue add-ons provide skills and instructions for customizing the assistant’s workflows.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Any agent

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00218	$0.15846
Opus 5.5	$0.00087	$0.06338
Sonnet 5.5	$0.00044	$0.03169
Haiku 4.5	$0.00022	$0.01585

Measured 2d ago against content hash d01cab3f9625, method: parsed. Prices are Anthropic first-party input rates as of 2026-10-07, from the pricing page.

Security

Grade A, and why

vibe scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Vibe CLI Self-Awareness

You are running inside Mistral Vibe, a CLI coding agent built by Mistral AI. This skill gives you full knowledge of the application internals so you can help the user understand, configure, and troubleshoot their Vibe installation.

Going Deeper

For facts not covered here, fetch the README: https://github.com/mistralai/mistral-vibe/blob/main/README.md It tracks the latest release, so check vibe --version before relying on it for anything version-specific. Point the user at https://docs.mistral.ai/vibe/code/overview for human-readable docs.

VIBE_HOME

The user's Vibe home directory defaults to ~/.vibe but can be overridden via the VIBE_HOME environment variable. All user-level configuration, skills, tools, agents, prompts, logs, and session data live here.

Directory Structure

~/.vibe/
  config.toml          # Optional user configuration, created on first saved setting
  hooks.toml           # User-level hook definitions
  .env                 # API keys and credentials (dotenv format)
  vibehistory          # Command history
  trusted_folders.toml # Trust database for project folders
  connector_bootstrap_cache.json # Short-lived connector discovery cache
  agents/              # Custom agent profiles (*.toml)
  prompts/             # Custom prompts (*.md)
  skills/              # User-level skills (each skill is a subdirectory with SKILL.md)
  tools/               # Custom tools (<name>.py); descriptions in tools/prompts/<name>.md
  logs/
    vibe.log           # Main log file
    session/           # Session log files

~/.agents/
  skills/              # Additional user-level skills directory

Project-Local Configuration

When in a trusted folder, Vibe also looks for project-local configuration:

.vibe/config.toml - Project-specific config (overrides user config)
.vibe/hooks.toml - Project-specific hooks (requires trusted folder)
.vibe/skills/ - Project-specific skills
.vibe/tools/ - Project-specific tools (<name>.py); a prompts/<name>.md beside them describes the custom tool <name>. Same tools/*.py + tools/prompts/*.md layout as the builtins.
.vibe/agents/ - Project-specific agents
.vibe/prompts/ - Project-specific prompts
.agents/skills/ - Standard agent skills directory

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
